CVE-2024-26599: pwm: Fix out-of-bounds access in of_pwm_single_xlate()

In the Linux kernel, the following vulnerability has been resolved: pwm: Fix out-of-bounds access in of_pwm_single_xlate() With args->args_count == 2 args->args[2] is not defined. Actually the flags are contained in args->args[1].

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel bug in PWM device-tree handling. Under certain parsing conditions, the kernel reads outside the provided argument array. The sources do not state impact, CVSS, or active exploitation, so business urgency depends on affected kernel use and vendor guidance.

Executive priority

Handle as a kernel maintenance item, not an emergency, unless critical products run affected kernels with PWM-dependent hardware. No active exploitation is supported by the provided sources, but kernel memory-safety defects deserve timely patch tracking.

Technical view

The flaw is an out-of-bounds access in of_pwm_single_xlate(). When args->args_count equals 2, args->args[2] is undefined; the flags value should be read from args->args[1]. Linux stable commits are referenced as the resolution.

Likely exposure

Exposure is likely limited to Linux systems running affected kernel versions and using PWM device-tree translation paths, commonly relevant to embedded, appliance, and hardware-integrated Linux deployments. Source data is incomplete for broader reach.

Exploitation context

The provided sources do not report active exploitation, public exploit availability, or KEV listing. They also do not describe attacker prerequisites or practical impact, so exploitability should be treated as unconfirmed.

Researcher notes

Evidence supports a bounds/indexing defect in Linux PWM device-tree parsing and references four stable commits. The bundle lacks CVSS, CWE, impact detail, exploit prerequisites, and distribution-specific fixed versions, limiting severity confidence.

Mitigation direction

  • Check your Linux vendor or distribution advisory for CVE-2024-26599.
  • Update to a kernel release containing the referenced stable fixes.
  • Prioritize embedded or hardware-integrated systems using PWM device-tree configuration.
  • Backport the upstream fix only through normal kernel maintenance processes.
  • Track vendor release notes for impact and regression guidance.

Validation and detection

  • Inventory Linux kernel versions across affected assets.
  • Compare deployed kernels against vendor fixed-version advisories.
  • Review kernel package changelogs for CVE-2024-26599 or the stable commit IDs.
  • Test updated kernels on representative PWM-dependent hardware.
  • Monitor post-update logs for PWM or device-tree initialization regressions.
